Gramatically, it actually is fairly well written. I'll give it that. The only problem is that, out of every character featured, only one or two are still pretty much in-character. It almost seems like Korra has been chickified
. She's much wussier than normal, but I guess that, if you try, it can be Hand Waved
as her just being nervous about having what might be her first long-term boyfriend. I absolutely hate seeing someone who is so strong and powerful in-series ruined. While Abuse Cycle might not be like How I Became Yours
in quality, it definitely will be come as well known for the same reason: destroying good characters by making them total monsters.
